Brief Summary

This study aims to determine whether ultrasound guided ESP block at 2nd thoracic vertebrae is non inferior to ultrasound guided ICBN block as adjunct to supraclavicular brachial plexus block in achieving complete sensory blockade of the medial upper arm during AVF superficialization

Conditions

ESRD (End Stage Renal Disease)

Keywords

AVF superficialization; Intercostobrachial block

Outcome Measures

Primary Outcomes (1)

• Proportion of patients achieving complete sensory blockade during AVF superficialization

  No discomfort and no need for sedation or conversion to general anesthesia

  baseline then at 15,30,60,120 minutes intraoperative assessment for vital signs and sensory blockade

Secondary Outcomes (4)

• Time to achieve complete sensory blockade.

  Time for complete sensory blockade in minutes within 30 minutes

• Patient's satisfaction (assessed using Likert scale).

  At the first 24 hours

• Total opioid consumption in 24 hours

  in the first 24 hours

• The visual analog scale(VAS)

  in the first 12 hours

Study Arms (2)

Ultrasound Guided Intercostobrachial Nerve Block

ACTIVE COMPARATOR

1. Position: patient supine with arm abducted. 2. Ultrasound setup: High frequency probe positioned at upper axillary region. 3. Technique: Needle will be advanced into subcutaneous tissue, in-plane to target intercostobrachial nerve near axillary artery. 4. Drug: 10 ml of 0.5% bupivacaine.

Procedure: Ultrasound Guided Intercostobrachial Nerve Block

Ultrasound Guided Erector Spinae Plane Block at T2 level

ACTIVE COMPARATOR

1. Position: patient sitting or in lateral decubitus. 2. Ultrasound setup: High frequency linear transducer will be placed in a parasagittal 2-3 cm lateral to spinous process at T2 level, erector spinae muscles will be identified superficial to the tip of T2 transverse process, patient's skin anesthetized with 3 ml of 2 % lidocaine subcutaneously, the tip of the 22- gauge 80-mm block needle (Sonoplex, Pajunk Medical, Geisingen, Germany) needle will be placed into the facial plane on the deep (anterior) aspect of erector spinae muscle. location of needle tip will be confirmed by visible fluid spread lifting the erector spinae muscle off the bony shadow of the transverse process then 10 ml of 0.5% bupivacaine will be injected into the facial plane that will be confirmed by visible hydrodissection .
